The universe may be far less crowded than we thought. Scientists have created a new theory that reduces the estimated number of the most distant galaxies in the universe by 10 to 100 times.
Researchers have uncovered unexpectedly hungry little black hole monsters.
A monster black hole woke up for the first time in 26 years-and it was hungry.
Black holes may actually be ideal labs for studying dark matter
NASA has taken a closer look at the "teenage years" of quasars. Using the Hubble Space Telescope, astronomers have uncovered the early formative years of the brightest objects in the universe.
Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, the brightest objects in the universe.
Supermassive black holes can be found at the centers of every large galaxy. Now, ALMA has managed to "weigh" one of these supermassive black holes.
Black holes may be more complicated than we originally thought, and may not be the ruthless "killers" scientists once believed.
Scientists have discovered something startling just outside a supermassive black hole. They've spotted a rear-end collision between two high-speed knots of ejected matter from the black hole.
Scientists have found that the massive explosions that mark the end of a star's life work with supermassive black holes to sweep gas out of a galaxy's star-forming factory.
Scientists have gotten the best view yet of a dusty gas cloud, G2, after it made its closest approach to the supermassive black hole at the center of the Milky Way.
One of the most powerful events in the universe occurs when two black holes collide. Now, scientists have taken a closer look at this event and have learned a bit more about what happens when two orbiting black holes become one.
